问题 I don't know why this code doesn't work: Dim a a = InputBox("What time do you want?") If InStr(a, "pm") Then (Replace(a, "pm", "")) a = a + 12 c = MsgBox(a, 0, Time) WScript.Quit Else End If b = MsgBox(a & form, 0, "L") Whenever I try to start it, it responds with: "Error: Expected Statement" Is it because the Replace statement isn't right or because there's a mistake in the rest of the script? 回答1: When you try to run that code you should get the following error Microsoft VBScript

问题 Say I have a text file: I love bananas. <age> 23 </age> years old. I like beaches. All I want to do is open said file and change the age to 24 or 25. Any way to do that in Java WITHOUT reading a writing the whole file? I know its possible with buffered reader and writer, but I am looking for a less memory intensive way when the file gets to be huge. 回答1: Short answer: no. Long answer: Not really. If you know that the text you're inserting directly replaces the text you're removing you could

C#去除HTML标签

Regex .Replace(html, "<[^>]+>" , "" ); strText = System.Text.RegularExpressions. Regex .Replace(strText, "&[^;]+;" , "" ); if (length > 0 && strText.Length > length) return strText.Substring(0, length); return strText; } 这个方法可以实现去除html标签的功能。 Length参数可以根据传入值取固定长度的值。用于生成文章摘要比较方便。 来源: CSDN 作者: dearbaba_8520 链接: https://blog.csdn.net/dearbaba

JavaScript trim函数大赏

本小妞迷上赌 提交于 2020-01-28 05:00:04
W3C那帮人的脑袋被驴踢了,直到javascript1.8.1才支持trim函数(与trimLeft,trimRight),可惜现在只有firefox3.5支持。由于去除字符串两边的空白实在太常用,各大类库都有它的影子。加之,外国人都很有研究精神,搞鼓了相当多实现。 实现1 String.prototype.trim = function() { return this.replace(/^\s\s*/, '').replace(/\s\s*$/, ''); } 看起来不怎么样,动用了两次正则替换,实际速度非常惊人,主要得益于浏览器的内部优化。一个著名的例子字符串拼接,直接相加比用Array做成的StringBuffer还快。base2类库使用这种实现。 实现2 String.prototype.trim = function() { return this.replace(/^\s+/, '').replace(/\s+$/, ''); } 和实现1很相似,但稍慢一点,主要原因是它最先是假设至少存在一个空白符。Prototype.js使用这种实现,不过其名字为strip,因为Prototype的方法都是力求与Ruby同名。 实现3 String.prototype.trim = function() { return this.substring(Math.max(this
